LUBRICATING SYSTEM.

memos..

Figure l is a perspective vien7 showing my system in one of its simplestforms; and

Fig. 2 is a transverse vertical section taken through one of the standpipes.

The object of this invention is to'provide a simple apparatus forsupplying a liquid lubricant to a series of bearings in uniform orregulated quantities, whether said bearings be in the same plane or not,as more fully hereinafter set forth.

The main supply pipe ais connected to any suitable apparatus forsupplying oil under pressure, an elevated tank o being shown in theaccompanying drawings as an exarnple. A manually controlled valve c isplaced in this pipe at any suitable point between the source and theseveral delivery nozzles. At intervals along the supply pipe a beyondthe valve is a series of stand pipes d, Whose lower ends are inconnection with the interior ot' the supply pipe and Whose upper endsare each connected pipe e, these delivery pipes being arranged toincline downwardly from every point of connection to the stand pipes.

lt will be observed that when the valve o is opened, the supply pipe andstand pipes will be filled with oil and that as the level rises .in theseveral stand pipes the oil `will flow over into 4the delivery pipe cand down these pipes to the respective bearings. These pipes arepreferably of bendableI tubing so that they may be adjusted so as todeliver. the oil properly to the bearings, and it is yobvlus that thesedelivery pipes may be of varyincf length and ma be bent to deliver theoi atifarying leve s, but in all cases the point at which the oil passesfrom the stand pipe to the delivery pipe will be'on the samelevel in allthe stand pipes, se that when any oil is delivered into the supply pipethe oil in all the stand pipes Will rise and delivery will take place ineach one of thestand pipes, to the end that all the bearings will besimulta ncously oiled and an` approximately uniform Specification@Letters Fatent.

quantity of oil will be supplied to each bearing, provided the standpipes are of the same ulterior diameter.

It will be observed that not only must the delivery points in the standpipes be on the saine level, but also that the delivery pipes shallincline downwardly from the delivery points, so thatthe oil willgravitate to the point of exit. Should it be desired to stop thedelivery of oil to any one bearing, the malle-ability of the deliverypipe will permit it to be bent upwardly far enough to bring its exit ornozzle end above the level of the `liuid in the stand pipes, whereuponthe decated farther oil from the supply as a sirn,

ple way of accomplishing this graduated feed, l may choke the supplythrough the stand pipe y bending or pinching the same, as slioivn at@ in2, in which manner it will be possi le to choke each stand pipe to asufiicient degree to give to each a. supply of oil especiallyladaptedfor the particular bearing which it is to sup ly. ln this mannnera very large number o? varying in height and distance with respect toeach other and the source of supply, may be properly lubricated by thesimple act of operating a single valve between the source of supply andthe first one of 'the series of delivery devices, it being understoodthat in all cases the delivery oints in all the stand pipes shall be noton y at a common level, but also above the level of the highest bearingthat is to be lubricated.

Any suitable number of lsupply ipes may be connected to the source ofsupp y, so long as each one is controllable by its own valve; have'shownat g two additional supply pipes, to each of which may be connectedanother series of delivery devices arranged to deliver atthe same levelor at a higher level than the one illustrated, provided in all casesthat the pressure at the source shall be suilicient to force the oil tothe tops ci the stand pipes.

In most cases a proper oiling of the bearings can be secured by simplymomentarily openinpr the valve o at intervals, but it will bearings,greatly he understood that this vei've .may he kept, slightly openduring the entire time the me elxiiiery is running, so that the deliveryim@ les constantly drop oil into their respective bearings. s

lim/ing thus described my invention, What l claim is:

i. 4Iii :m apparatus for lubricating, a plurzility of bearings, esoui'ce or supplying oil luider pressure, a. supply pipe connectedthereto and provided with e valve, and a series el oil deliveringdevices 'distributed along the supply pipe et intervals beyond saidvulve, each o i' these delivery devices consisting oi' a stand pipeconnected to the .supply pipe :it its lower end and connected at itsupper end to a delivery pipe, seid delivery pipe inclihing downwardlyfrom the point of connection to the stand pipe and the points ofdelivery' from the Stand pipe into said delivery pipes being all in thesame horizontal plane, ior the pui'pose set iieth.

in an apparatus forlubrieating, e plurality of heariifigsY e source forsupplyiiig memos oil undef p. essere, e supply pipe connected theretoand provided with a valve, and a series of oil delivering devicesdistributed along; the supply Apipe at intervals beyond seid valve, eachof these delivery pipes con' sisting of :i stand pipe connected to thesupply pipe at its lower end and connected at its upper` end to adelivery pipe,`said delivery pipe inelining-downwardly 'from the pointof connection to the stand pipe and the` points of delivery from thestand ypipe into seid delivery pipes heilig all in the same horizontalpiene for the purpose set forth, ineens being provided for choking o1restricting the supply of oil through those stand pipes which arenearest to the source of supply. l
